Hot on the heels of its trifecta of HSPA + smartphones (the Infuse 4G, Atrix 4G, and Inspire 4G), AT&T announced that both HSPA+ and LTE tablets are coming to its network in the second half of 2011. The first tablet is made by Motorola and features HSPA+ (or as AT&T calls it, 4G), Honeycomb, a 10.1-inch display. and a 1GHz NVIDIA Tegra 2 processor. The second tablet features LTE, but AT&T was reluctant to share more specifics. These will be joined by more HSPA+ devices in the first half of the year (5 to 7 devices total), and LTE devices in the second half of the year, including phones, tablets and modems.
